Outcomes after lung resection in renal transplant patients with pulmonary mucormycosis.

BACKGROUND: Pulmonary mucormycosis has been associated with high mortality (reported up to 100%) in renal transplant recipients. METHODS: This was a retrospective analysis of renal transplant patients with pulmonary mucormycosis between April 2014 and March 2020, who underwent surgical resection of the affected lung along with liposomal amphotericin therapy. Patients with lower respiratory illness features underwent chest X-ray, high-resolution computed tomography of the chest, and those with suspicious findings underwent analysis of bronchioloalveolar fluid and transbronchial lung biopsy. Patients with histological or microbiological evidence of mucormycosis were started on liposomal Amphotericin B. Tacrolimus and mycophenolate mofetil were stopped at the time of diagnosis. RESULT: Ten patients underwent combined management, while five patients were managed medically. At last follow up, seven out of ten patients (70%) who underwent combined management and two of the five patients (40%) who were managed medically, had a mean survival of 28.86 months (sd = 15.71, median = 25) and 14.17 months (sd = 12.21, median = 18), respectively, post-diagnosis of pulmonary mucormycosis. CONCLUSION: Surgical resection combined with antifungals in the perioperative period and decreased immunosuppression may improve the outcomes in renal transplant patients with pulmonary mucormycosis.

Experience With 15 Years of Laparoscopic Donor Nephrectomy: Review of 2500 Cases.

BACKGROUND: Laparoscopic donor nephrectomy (LDN) is considered the gold standard for live donor nephrectomies owing to lesser pain, shorter hospitalization, and earlier return to normal activities, yet it remains a technically challenging surgery. Repetition of a highly skilled task such as LDN should lead to improved performance reflected in shorter surgery times and a decrease in adverse events. METHODS: The records of over 2524 LDNs from February 2004 to June 2019 were evaluated for duration of surgery (from incision time to clamping of the renal artery) and occurrence of complications. RESULTS: The mean duration of surgery ± SD from incision to clamp time for the first 100 cases at the inception of LDN was 166.13 ± 33.28 minutes whereas it was 124.59 ± 35.91 minutes for the best 100 consecutive cases in 2015 with a decrease of 41 minutes duration of surgery from incision to artery clamping. The adverse events were accessory renal artery injury (n = 10), splenic laceration (n = 2), bowel and mesocolon injuries (n = 12), venous or arterial clip slippage (n = 4), inferior vena cava tear (n = 2) pneumothorax (during stapler application, n = 1), missing gauze counts (n = 1), chylous ascites (n = 1), ureteric thermal injury (n = 2), and renal parenchyma injury (n = 3). CONCLUSIONS: LDN is a technically demanding surgery where surgeon experience appears to affect operative metrics such as operative time. The occurrence of intraoperative complications appears to be acceptably low, although serious complications are a possibility.
